Chat

Chat Completions

Access 24 large language models — GPT, Claude, Gemini, DeepSeek, Grok, Llama, Mistral, and more — through a single OpenAI-compatible endpoint. One API key, one format, every model.

How it works

Synchronous

Chat returns the full response immediately — no task_id, no polling, no webhooks needed.

OpenAI-compatible

Uses the standard messages format. Drop in your existing OpenAI SDK code and just change the base URL.

Credit-based

Charged per request (not per token). Budget models from 1 credit, top reasoning models at 5 credits.

Quick start

curl -X POST https://journeyapi.co/api/v1/chat/completions \
  -H "Authorization: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-4o",
    "messages": [
      { "role": "system", "content": "You are a helpful assistant." },
      { "role": "user", "content": "Write a prompt for a sunset photo." }
    ]
  }'

Or use the OpenAI SDK — set base_url to https://journeyapi.co/api/v1 and your JourneyAPI key. No other changes needed.
